T 0 all ruhom it may. concern.

Be 1t known that I, GEoneE F. WINTER, a citizen of the United States, residing at y Los Angeles, in the county of Los Angeles and State of California, have invented a'new and useful Safety-Gate, of which the following is a specification. V

The objectof this invention is to increase the safety to passengers entering and leaving elevators or lifts or going through passways controlled by edgewise moving closures.

A serious source-of danger to such passengers arises from the forceful closing of heavy elevator doors by mechanisms such as pneumatic or hydraulic door closing apparatusnow coming into general use, and an object ofthis invention is to avoid all danger that a leg or arm of any passenger entering or leaving an elevator will be caught by the closing door;

The invention pertains to the construction of elevator doors and the provisionand arrangement of a buffer or buffers therefor.

Other objects of the invention are simplicity, strength and cheapness of construction.

Other objects, advantages and features of the invention may appear from the accompanying drawings, the subjoined detail description and the appended claims.

The accompanying drawings illustrate the invention.

Figure 1 is an elevation ofran elevator double door constructed in accordance with this invention and shown partly open.

Pneumatic operating apparatus is also in-' dicated diagrammatically.

. Fig. 2 is a fragmental elevation of a lower part of the door edge and buffer.

Fig. 3 is an elevation in section on line 00 Fig. 1.

Fig. 4 is a front elevation of of somewhat different construction.

Fig. 5 is a front elevation of a doubledoor of the character shown in Fig. 1 fully closed. I

i Fig. 6 is a fragmental elevational detail of closure frames and buffers at the lower mid dle part of Fig. 5; the doors being partly The frames of the edgewise moving closure means shown to close a passway or doorway Fig. 1, are constructed of U-shaped metal bars comprising the rear upright 1 and the horizontal bottom and top limbs 2, 3, of one edgewise moving door body or clobe accomplished without a double door sure a, and the rear upright 1 and the horizontal bottom and top limbs 2", 8, of the second door body Z).

r lVithin each of said frames is a grid, which may be made of any suitable form and is shown terminating in the forward marginal member a, which is parallel to the rear upright member 1. The horizontal members 2 and 3 project forwardly beyond the upright forward marginal member t and are provided with resilient buffer means 5 adapted to contact with opposed buffer means so that the closing of the door will The grids which terminate in the marginal members 4 be made of any suitable construction and are shown as opposing uprights 6 and 7 horizontal bars 7.

bodies are brought together, 'the space between the marginal bars 4: is such as to accommodate a limb as the leg, foot, arm or hand of a passenger or other person, so that no crushing effect will result from closing the door while the limb of a person entering, leaving or standing in the elevator, not shown, is in the passageway. This space may accommodate such portions of the body without allowing ingress or egress of the entire body; and in order to give more complete closing effect without injury. to limb of the passenger, yielding means indicated as a coiled spring buffer 8 is provided and is attached to the projecting portions 9, 10 of the lower and upper limbs of the door frame.

F or-convenience the ends of'the portions 9, 10 may be provided with crooks 11 to which theresilient buffers 8 are connected.

In Fig. 5 the resilient buffer is shown connected to projection 11 at the top of the edgewise moving closure 0 and when the two closures c, d shown in Fig. 5 are closedas shown in said Fig. 5, the resilient buffer 8 stands at the middle of the space between the marginal upright bars i and will be deflected by pressure upon the interposed limb; such space 12 between the upright bars 4 being of such width as to accommodate said limb and said width bein determined by the length of members 9 and buffers 5.

means of antifriction hangers l t and said doors are operated in practical use by any suitable means as the pneumatic apparatus 15 well known in the art and connected to the doors by any well known suitable meansway or passway 18, and'in'case the limb of any'person should be in the passway 18, at;

the closing of the same, the resilient bufier 8' will strike the limb that is in the way thus giving warning and then will yield without crushing the limb; l j lclaimz Y e n v I 1.
